Two more elevated radiation readings on Treasure Island

The U.S. Navy has completed its surveys of Treasure Island and found two more locations where higher-than-usual radiation levels were detected — one under an occupied house, a city official said Wednesday.

In all, the Navy found three places where radiation levels were higher than normal, said Bob Beck, development director at the Treasure Island Development Authority — but none were above a threshold, set by the Navy and the California Department of Public Health, that would raise health concerns.

The two most recent elevated readings were taken on July 29 and 30 — one under an occupied residential unit, and another under a storage shed, Beck said. He declined to disclose the exact locations, saying the Navy and city want to give the households “time to process” the information. Those residents have been offered the option to move, Beck added, and were told about the findings the day the readings were taken.

Beck said the city expects the Navy to investigate all three findings and “in all likelihood” remove whatever objects are causing the elevated readings. Details on the survey of the 1,100 housing units on the island will be released in the Navy’s final status survey report, Beck said, in early November.

“We are very glad to have the (surveys) completed, and to have this blank spot of information filled in,” he said. “And we are very glad that nothing unexpected was found.”
